Letting off coloured smoke flares, the protesters were later praised by the stars of the film for their strong message.

Shouting "it is our duty to fight for our freedom" the women refused to be moved as they completely took over the premiere.

An eye-witness told The Mirror: "A horn rang out 4 times and about a dozen women jumped over the barrier, laid down on the red carpet and linked arms and started shouting, 'David Cameron take note, dead women can't vote'."

And: "You say cutback we say fight back"

"Security tried to fight them back but couldn't keep control," the witness went on.

"They then tried to beg them to move but they refused. They got even more angry when called 'girls' shouting, 'we aren't girls, we are women'."

"Then a second barrier further in the park got broken down by protesters with megaphones."

Actress Helena was quick to praise the protest, saying: "I think it's marvellous. That is exactly what the suffragettes were about.

"Hopefully the film will inspire anybody who feels an injustice has been done, to be bold enough to protest."

According to Sister's Uncut the protest is a celebration of "women's struggles" and the "ongoing struggle for women's lives."

They wrote on the Facebook event page: "The film "Suffragette" will premier in London on the 7th October. The film depicts a struggle for women's rights that took place nearly 100 years ago, but we know that the struggle isn't over.

"When 2 women a week are murdered by violent men and services to support them are being destroyed by government cuts, women - especially black, trans and disabled women - are struggling to stay alive.

"Join Sisters Uncut at the premier to celebrate the history of women's struggles and our ongoing struggle for women's lives - because dead women can't vote."

Those down at the premiere admitted they completely stole the show and even drowned out an interview with the Pankhurst family - descendants of the iconic women's leader Emmeline Pankhurst- as they spoke at the premiere.

They reportedly didn't mind though with Helen and Laura Pankhurst - great granddaughter and great-great granddaughter of Emmeline - describing the protest as "fantastic".

The night - which kicked off this year's BFI London Film Festival - was delayed by around 20 minutes due to the demonstration, with stars including Helena Bonham Carter having to wait for the women to be moved.
